ROTARY ENGINE.

Specification of Letters Patent.

Patented Oct. 2, 1917.

Application filed July 12, 1916. Serial No. 108,878.

To all whom it may concern.

Be it known that I, FRANK NnAnINo, a citizen of the United States, residing at 62 West 93d street, borough of Manhattan, city of New York, county of New York, and State ofNew York, have invented a new and useful Rotary Engine, of which the fol lowing is a specification.

My invention relates to improvements in rotary engines to be operated by steam or any vapor, gas, explosive, or otherwise, or liquid, in which there are a number of segmental cylinders on a coupled shaft in two separate groups, each group set between independent adjustable bearings and each group having equal piston areas on opposite sides of the shafts in each group and the cylinders .of each group taking ,pressure simultaneously through a portion of the revolution and each group taking pressure inturn before the cylinders of the preceding group have exhausted. The said cylinders are provided with intake and exhaust ports and radially moving abutmentswhich are operated by the action of two eccentric disks set'on the main shaft, one disk is flattened for a portion of its perimeter and the other of correspondingly increased radius so that the distance from the center of a roller against the side of one. disk .to the center of a si-n'iilar roller against the opposite side of the other disk is always equal to the distance between the center of the said rollers measured across the circular portions through the axis .of rotation of the said disks. The said disks act against rollers mounted on cross-heads and the mechanism connecting the said cross-heads to the abutments causes the movement of the said abutments in the manner hereinafter described.

And the object of my improvements are, in a rotary engine:

First: A continuously applied pressure with the greatest effect.

Sesond: The elimination of the direct axial pressure from the drums and the pressure due to the reaction from the pistonsthe consequent reduction of friction in all parts and lessening of vibrations through the balancing of pressures.

Third: "The prevention .of piston leakage by the :radiallyand longitudinally expansive pistons.

Fourth: The two part abutments and the springs connected with them to prevent leakage and take up wear.

Fifth: The positive action of the abutments caused by the eccentric disks acting on the crossheads, connecting rocker arms, secondary rocker arms, cross connecting rods for reversed motion and the final rocker arms connecting to the abutment rod crossheads.

Sixth: The ability for roup and individual adjustment of a utment throw through the movable adjusting sleeves on the rocker arms and the adjusting nuts on the abutment rods. 7

Seventh: The prevention of pressure leakage through the abutment entries by the cylindrical stop valves.

Eighth: Th2 access to the drums. pistons and drnm keys, for their removal, repair, or replacemrmt through the removable ments. w

Ninth: The ability for automatic adjustment of the drums by the keys which are fixed in the drums and have some longitudinal movement in the keyways of the shafts.

Tenth: The ability to keep the shaft in center by the independent adjustable bearings.

- Eleventh: The ability to cut oil one group and allowance for variation of a'linement through the flanged and universal couplings.

I attain these objects by the mechanism illustrated in the accompanying drawings; lligure 1) is a plan view of the whole 1nachine slu'nving the groups of cylinders. Fig. (2) is a section taken on the lines 22. Fig. (3) is a section on the lines il-3 of Fig. (l).- Fig. (4) is a side view of the whole machine with guide standards cut away to show disks. Fig. (5) is a longitudinal section of one cylinder showing pistons cut away with keys, drums, and shafts in section. Fig. (6) is a section across one abutmeut showing hearings in cylinder heads and the two plates dovetailed together. Fig. (7) ,is a view at center showing the eccen tric disks and their connections. Fig. ,(8) is a sectional view of the adjustable main bearings. Fig. 9 is a view of C or C cut away in portion to show the relative positions of the pistons and the a-butments, the intake and exhaust ports, the drum keys, abutment stop valves, abutment rods, crossheads, guides, disk connections to rocker arms, .reverse arms with connecting rods, removable segments, &c. Fig. l0 is a view of G or C similar to that shown in Fig. 9.

Fig. (11) is asectional View of the abut-' upon which all parts are mounted, C C C 30 C and C are the cylinders, C

and Ctform one group and G and C form a second group.

C and C have pistons on the same sides of the shaft and C 'has a piston on the opposite side of the said'shaft, the area of the piston of C being equal to thesum of the piston areas of C and C C and C have pistons on one side of the shaft and C has-a piston on the opposite of the said shaft the area of the piston of 0 being equal to the sum of the areas of a the pistons of C and C The shaft S is mounted in the adjustable bearings D and carries the drums J within the cylinders.

The said drums J are keyed to the shaft S by the keys EH which are firmly fixed between the aws of the said drums J and are fitted to slide in the key ways of the shaft S and the said ,ke'y ways being some what longer than the keys.

The backs of the outward from their centers to the cylinder heads and form seats or beds for the piston wings E each of which is composed of two oppositely symmetrical parts which are halved and lapped 'for' a-portion of their length. The two said parts forming one wing are each cut away for a short space atthe center of each wing leaving openings in which springs T are placed to hold the two parts of each wing against the cylinder heads and small openings or ports P. in the piston jaws on the pressure side admit pressure to force the said wings against the heads and barrels of said cylinders by action in the spaces which are occupied by the said springs. 1 v

The shaft coupling K is flanged to permit disconnection of one group and is packed somewhat apart with'plates which may be increased or removed for adjustment. I The universal coupling K permits some variation of alinementof the two groups.

' The disks F and F are circular for somewhat more than 180 degrees the said circular portions being on opposite sides of the shaft S. F is flattened opposite its circular ortion and F corres ondin l increased in its eccentric portion so that the distance from the center of a roller against the side of one disk to-the center of a similarroller against the opposite side'of the other disk is always equal to the distance between the centers of the said rollers measured across the circular portions through the axis of rotation of the said disks.

' The action of the circular portion of F keys E are inclined passage of the'pistons.

Bearing against opposite sides of the.

disks F and F are t e rollers N, mounted on the crossheadsv H which slide on the guides L The said crossheads H v are connected by therods R, from the sides of one disk to the opposite sides of the other disk so as to keep the said rollers'constantly against the said disks. The said rods R are provided with springs T between the heads of said rods and their crosshead connections to ease the action of the said roller against the said disks.

-The crossheads acting on the disk F are connected by rods R to sleeves clampedby screws on the rocker armsGfi, so that said sleeves may be moved on the said rocker arms for group adjustment.

' The rocker arms G are,

along the abutment sides of C and C and G and C and have fixed thereon the double rocker arms G, for moving the abutments of cylinders C C C and C H Upon the shafts S are alsofixed the rocker arms G which are coupled to the fixed on the shafts S which are mounted in bearings rods R extending across the engine and connected to the sleeves clamped with screws upon the rocker arms-G ,'saicl rocker arms G bemgfixed on the under sides of the shafts S upon said shafts S are also fixed the double rocker arms G for moving the abutments of cylinders C and C simultaneously with thoseof the other cylinders of their respective groups.

The connect ons of the rods R and R to the sleeves on the rocker arms G and G are formed by pins which extend through two parts of the said rods, the sleeves and slots in the rocker arms permitting movement of the said pins but the bearings of said pins being in the saidsleeves.

The outer ends of the rocker arms G pass through the channeled circular disks U, I

which are seated in bearings for them in the sides of the crossheads H and the covers of said disks which are bolted to the crossheads H The crossheads, H are pierced by the abutment rods R and are mortised' to fit nuts on thesaid rods R said mortise also makes space for springs T which press against the-said nuts and'the' outer part'of the mortise. abutment rods during withdrawal and the springs T cushion thethrustof the abutments as they strike the drums J. i

The crossheads H 's'lid'e The said nuts holdthe said upon the movable segments V, and the abutment chambers A are bolted on to an extension of the cylinders. The abutments are each in two parts one A which inclose the T end of the abutment rods and which slide in grooves in the cylinder heads. A, are plates which bear on the plates A and have a dove tailed lug through the plates A against the said lugs are springs T, which abut against sections of the plates A said springs forcing the parts A against the drums J when the abutments are closed.

The cylindrical metallic spindle packing A, extends across the abutment plates A and are placed loosely in chambers in the abutment extensions on the pressure sides and are provided with ports P, which ad-' mit pressure and press the said packing A" firmly against the said abutments to prevent leakage in the abutment chambers.

The removable segments V, are between the exhaust ports X and the abutments.

The intake ports P are located so as to admit pressure behind the pistons after the abutments are closed.

In operation the pressure is admitted through the entry ports of the group in which theabutments are closed forcing the pistons of that group around through their portion of the revolution and carrying the pistons and abutments of the other group around to the points where the last said group takes action vand the exhaust of the preceding group is reached, the groups taking action in rotation.

The group following in the group action, takes pressure before the group preceding it has exhausted insuring continuous pressure action without any dead point.
